Abstract

We show the ability of calcium barium niobate as a nonlinear material to produce conical second harmonic generation in a broad frequency range. The nonlinear properties of this system are based on the broad sized microdomain distribution appearing naturally in the as-grown crystal. The large angular deflection obtained for conical second harmonic generation allows considering this system as a nonlinear prism with variations in the second harmonic generation angle as large as 35° in the wavelength range of 430-660 nm. © 2009 American Institute of Physics.
